APPARATUS FOR MOI STENIN CARBURE'ITED MIXTURES FOR GAS-ENGINES.

' I A 4. Application filed To all whom it may concern: j A Be it knownthat .1, WILLIAM- MILLARD, a subject of the King of Great Britain,residing at the borough of Manhattan, city, county, and State of NewYork, have .in-

vented certain new and useful Improvements in Apparatus for MoisteningCarbureted Mixtures for Gas-Engines, of which reted mixture that isburned' in the working the following is a specification, reference beinghad t the accompanying drawings.

. This I invention relates to improvementsv in apparatus forimpregnating a combustible gas with water vapo'i, and particularly toimprovements in apparatus by means of which air-is made moist andis'then incor porated, in a moist condition, in a carbuvl cylinder of agas-engine, or likem'otor, of

an automobile; and an object of this invention is to provide anapparatus of the char-. acter just described which will. prove simple inconstruction, comparatively .cheap in manufacture and efficient inoperation. and

use. Another object of this "invention is to provide an apparatus of theli nd hereinbefore referred to by means of which the resultsobtainedwill be uniform n character,

Other.features of thisinventionwill be referred to hereinafter. 1

In the drawings illustrating the principle of this invention and thebest mode now known to me of applyingthat principle,

Figure 1 is a central vertical section-through the tank or reservoir ofthe air-moisten'er; F ig. 2 illustrates the latter connected to theintake manifold of a gas-engine or like motor; Fig. 3 illustrates amodification of the construction shown in Fig. 2, the air-mo is' tenerbeing connected to the carbureter; Fig.

it shows, -in central vertical section, a modified torm'of theair-moistener illustrated in Fig.1, the admission of the airbemg-co-ntrolled by a valve arranged over an air opening in the base ofthe reservoir or receptacle that 'holdsthe Waterfors0lution; Figs. 5 and6 are fragmentary sections in which a flap valve and .a ball valve,respectively, are shown; and Figs. 7 and 8 are plan views showing thedisklike check valve of Fig. 4: and the flap valve of Fig. 5,respectively.

a denotes a cup-shaped, transparent vessel which serves as a receptaclefor holding water or a suitable solution 6 andthe exterior of the mouthof Which is formed with Specification of Letters Patent.

In the latter, there isformed "an opening f which is normally kept closed by means of 'astopper 9, which is screwed thereinto and which, when it is desired to-replenish the supply of Water 6 in the ves- 'between the mouth ofthe'vessel a and the inner face of the'cover d and serves to make thejoint between the vessel "and its cover air-tight. Near'the center ofthe cover (I, there is formed a boss J1, having, in its top, a socket orcavity h. The bottom it of the socket it serves as a supportffor'thevalve i,

which is screwed into the bottom 71, and

which is formed with a disklike head 2",

downwardly from the boss h, there extends I anair-tube 7', the centralpassage. 7" in which communicates at its-,upper end with ports formed inthe bottom it of the socket h. By turning the milled head i of. thevalve 2', the position of the same may be so adjusted asto closeentirely the ports is, leave them fully open or close-them onlypartially, whereby'the amount of air admitted to the air-passage y" maybe regulated. A vertically-extending leaf-spring m is arranged adjacentto the boss h and is provided, at its upper. end, with a detent or catchm that is designed to engage automatically in the milled, peripheralsurface 2' of the valve-head z" and serves thus to retain the valve inits adjusted position. The lower end of up. air-tube j is formed withopenings or ports .j-through Which the air escapes from the air tube-jand passes into the water I), through which the air flows up- Jan/27,1920.

air-opening a is controlled by a flap valve r secured to the bottom ofthe receptacle (1 b means of the fastener r. In Fi 6 there is shown amodified form in which the boss h projects downwardly from the base ofthe vessel a, while escape of water through the airypassage s isprevented by the ball-shaped check-valve s, the casing s""of which isformed with ports t for the flow of the incoming air into the water Z).

Instead of water, a mixture-of water with alcohol may be used to moistenthe air; and

a solution of hydrogen peroxid may be made to serve the same purpose.Other suitable solutions will readily suggest themselves to all skilledin this art. 4

I claim:

A unitary air-moistening device comprising a reservoir adaptedto containliquid and air and having formed directly in and by one of its walls apassage intermediate the lower portion. of its interior and the at-"mosphere, a valve applied directly to and carried by the said wall ofthe reservoir and which controls the flow of air through said passageinto the lower portion of'tlie reservoir, and a conduit carried by onewall of the. reservoir, in communication with the upperportion of theinterior thereof and capable of direct connection to a conduit forca-rbureted air.
